Parallax Chrome
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or semi-angle of inclination between those two lines. Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances. To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term ''parallax'' is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit. These distances form the lowest rung of what is called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial objects, serving as a basis for other distance measurements in astronomy forming the higher rungs of the ladder. Parallax also affects optical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiprocessing
Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined ( multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.). According to some on-line dictionaries, a multiprocessor is a computer system having two or more processing units (multiple processors) each sharing main memory and peripherals, in order to simultaneously process programs. A 2009 textbook defined multiprocessor system similarly, but noting that the processors may share "some or all of the system’s memory and I/O facilities"; it also gave tightly coupled system as a synonymous term. At the operating system level, ''multiprocessing'' is som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scribbler (robot)
The Scribbler is a small, low-cost fully programmable intelligent robot with multiple sensor systems. It is capable of auto navigation and interaction with its environment. The Scribbler is a combined effort of three companies: Parallax Inc., Element Products Inc., and Bueno Systems Inc. In May 2010, the Scribbler was selling for a retail price of around $100 USD. A newer version of the Scribbler, Scribbler 2, came out in the fourth quarter of 2010. The Scribbler has a built in BASIC Stamp 2 microcontroller brain. For inputting sensory information, the Scribbler has three photoresistor light sensors, infrared emitter, and infrared detector. Additional add-ons can be bought to give the robot more capabilities through the serial port. For example, a bluetooth emitter/receiver or a wireless card can be bought to interface with the robot. The Scribbler can be programmed through any BASIC Stamp Editor program, or through a GUI-style interface, provided on Parallax's website. This ...

Ottawa, Illinois
Ottawa is a city located at the confluence of the navigable Illinois River and Fox River in LaSalle County, Illinois, United States. The Illinois River is a conduit for river barges and connects Lake Michigan at Chicago, to the Mississippi River, and North America's 25,000 mile river system. The population estimate was 18,742, as of 2020. It is the county seat of LaSalle County and it is the principal city of the Ottawa, IL Micropolitan Statistical Area. History Ottawa occupies a place on the Illinois River that has long been one end of a portage trail between the Mississippi River and Lake Michigan. Here the river was reliably deep enough for canoes. The North Portage Trail connected the site over land and water to the Chicago River. Ottawa was the site of the first of the Lincoln–Douglas debates on August 21, 1858. During the Ottawa debate, Stephen A. Douglas, leader of the Democratic Party, openly accused Abraham Lincoln of forming a secret bipartisan group of Congressm ...

Nuts And Volts
''Nuts and Volts'' is a bimonthly American magazine for the hands-on hobbyist, design engineer, technician, and experimenter. It has been published by T&L Publications since 1980 and leans heavily toward microcontroller and digital electronics projects. The magazine is based in Corona, California. History The primary issue of ''Nuts and Volts'' was available in 1980. At first it was intended as newsprint, all advertising magazine that was typically distributed for free. The magazine was published on a monthly basis. Over the next few years, the monthly continued to grow in distribution and publicity. However, not much changed until February 1992 when ''Nuts and Volts'' changed to a tabloid format and began to make the shift to a more magazine-like format. Editorial features were added along with monthly columns and projects for electronic DIYers. Since then, ''Nuts and Volts'' has matured into one of the most well-liked and pertinent magazines for the electronics hobbyist in t ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boe-Bot
BOE–Bot is short for Board of Education robot. It is the trade name of a robot kit that is used in junior high, high school and college robotics classes. It consists of a main circuit board (the Board of Education) and breadboard, a plug–in BASIC Stamp microcontroller, two servo motors to drive the wheels, and an aluminum chassis that the parts bolt onto. Students can use Erector set parts, Lego blocks, and additional servos to build custom projects. The BOE-bot has been manufactured and sold by Parallax Inc since 1998. Main components The green detachable main circuit, mounted on the top of the robot is called the ''Board of Education''. The microcontroller which plugs into a socket on the green circuit board is called the BASIC Stamp . The BASIC Stamp is programmed in PBASIC. The rear wheel is a drilled polyethylene ball held in place with a cotter pin. Wheels are machined to fit on the servo spline and held in place with a screw. The BASIC Stamp is easy to program.

PBASIC
PBASIC is a microcontroller-based version of BASIC created by Parallax, Inc. in 1992. PBASIC was created to bring ease of use to the microcontroller and embedded processor world. It is used for writing code for the BASIC Stamp microcontrollers. After the code is written, it is tokenized and loaded into an EEPROM on the microcontroller. These tokens are fetched by the microcontroller and used to generate instructions for the processor. Syntax When starting a PBASIC file, the programmer defines the version of the BASIC Stamp and the version of PBASIC that will be used. Variables and constants are usually declared first thing in a program. The DO LOOP, FOR NEXT loop, IF and ENDIF, and some standard BASIC commands are part of the language, but many commands like PULSOUT, HIGH, LOW, DEBUG, and FREQOUT are native to PBASIC and are used for special purposes that are not available in traditional BASIC (such as having the Basic Stamp ring a piezoelectric speaker, for example).
